higgo Posted January 4, 2012 Report Share Posted January 4, 2012 Hi everybody, i am new to this site, but wondered if any body can help with my dilema, i have a ossa 250 mar which is running a standard bore, did a compression test this evening and got a reading of 77psi. Squirted some oil down the bore and then got a reading of 88 psi. Can anybody tell me what psi would indicate a healthy engine. Thanks HIGGO.
